Abstract

The invention contemplates a binocular telescope wherein a bridge interconnects offset arms of separate individual telescope housings on spaced articulation axes, to enable compact folding of the telescopes along opposite sides of the bridge, when not in use. A first single control element provides ganged positioning control of corresponding focusing optical elements within both the respective telescope housings, and a second single control element provides independent adjustment of the focusing optical element within one to the exclusion of the other telescope housing. In the specific disclosed embodiment, a spring-loaded lost-motion connection between the ganged control structure and the mount for the focusing optical element enables the second single control element to provide for adjusted single-eye corrective accommodation without affecting the ganged focusing displacement produced by adjustment of the first single control element.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to binoculars having a double-hinged coupling bridge between two monoculars, in which in each monocular casing an optical element used for adjusting the focus is provided. is supported within the casing by an axially movable support member, the support member being coupled to an axially movable pivot pin inserted through the web into the pivot shaft; The two pivot pins move together axially by the same amount via the first drive knob to adjust the focus.

In the case of this type of binoculars, in addition to adjusting the focus of two monoculars together, it is desirable to have a focusing method that affects only one monocular, and by this method, it is possible to adjust the difference in diopter of the operator. can.

In the case of single-hinge binoculars, a drive knob is provided on the edge of the hinge bridge on the side facing the operator's eyes for adjusting the focus of the two monoculars together, and a drive knob is provided on the other edge of the hinge bridge for adjusting the focus independently. It is known to provide other drive knobs. Such a solution cannot be transferred to binoculars with a double-hinge bridge and is also operationally inconvenient.

From the description of West German Patent No. 2233055,
Binoculars with a double-hinged bridge are known, in which the joint focusing of the two monoculars is carried out by means of a drive knob arranged in the connecting bridge, and the difference in diopter of the operator is In order to compensate for this, the eyepiece or objective lens can be configured to be independently adjustable. This independent adjustment is normally caused by a rotating ring on the monocular. Apart from the difficulties encountered in sealing the monocular by adjusting the eyepiece or objective individually, this solution is also operationally inconvenient.

By the way, an object of the present invention is to provide binoculars having a double hinge connecting bridge between two monoculars.
An optical member that allows an operator to perform both joint focus adjustment and independent focus adjustment without removing the binoculars from his eyes, and that is disposed between the eyepiece lens and the objective lens during both of these focus adjustment processes. This relates to configuring the system so that it is only necessary to move it.

The problem is that in binoculars of the type described above, a first drive knob is arranged on the side of one pivot axis facing the viewer, and a first drive knob on the side of the other pivot axis facing the viewer. 2 drive knobs are arranged,
The first drive knob is connected to a sleeve and a threaded pin forming a threaded joint for converting rotational motion of the drive knob into linear motion in the axial direction, and further via a threaded coupling member coupled to the threaded pin. coupled to a first pivot pin, the protrusion of which projects into a plate movably supported axially in the coupling bridge, and a second pivot pin inserted into the pivot. and is elastically coupled via a spring to the sleeve that moves in the axial direction via the plate, and the second drive knob is movable in the axial direction and the tongue that constitutes the coupling member. coupled to a cylindrical pin via a bifurcated member rotating therewith, the cylindrical pin being rotatably and movably supported in the sleeve, and further coupled to the cylindrical pin on an opposite side of the coupling member; The solution is that the threaded pin is threadedly connected to the threaded sleeve in the second pivot pin in order to convert the rotary movement into a linear movement.

Since the operator holds the binoculars with both hands during observation, the operator can:
The two drive knobs can be operated in a simple manner without removing the binoculars from the eyes.

The operator can jointly adjust the focus, ie adjust the binoculars to the desired viewing distance, by rotating the first drive knob. In this case, the two pivot pins and their associated focus adjusting members move axially by the same amount simultaneously in the two monoculars.

When operating the second drive knob, only the second pivot pin and the focus adjustment member associated therewith are moved in the axial direction. In this case, the distance between the focusing member connected to the second pivot pin and the member used together to transmit the focusing movement varies in practice.

Embodiments of the present invention are illustrated in FIGS.
Three figures will be explained in detail.

In FIG. 1, the two monocular casings are
2 and 2', the casings are interconnected via a double-hinged connection bridge 1. A drive knob 6 is provided on the hinge shaft 12, which is used to focus the two monoculars together. Other hinge shaft 12'
At the top, a drive knob 30 is provided, with which the monocular 2' is separately focused to adjust for differences in diopter of the operator.

In order to adjust the focus of the two monoculars 2, 2' together, the optical elements 3 and 3', respectively arranged between the objective lens and the eyepiece in the monocular, are simultaneously moved in the axial direction. In order to focus the monocular 2' separately, only the member 3' arranged in the monocular is moved in the axial direction. This method of action will be explained in more detail with reference to FIG.

The drive knob 6 is connected by a screw 7 to an axle pin 8 whose lower part is configured as a sleeve 9 with an internal thread. In the sleeve,
A screw pin 10 fixed in the rotational direction is introduced,
The lower part of the screw pin is fixedly connected to the first pivot pin 5 via a screw connection member 11 . The pivot pin is mounted axially movably in a pivot shaft configured as a hollow shaft 12 . The lower end of the pivot pin 5 is connected to the web 4a of the support member 4 having the focus adjustment member 3. Furthermore,
The web 4a is provided with a hole 13 into which a pin 14 integral with the casing projects, so that the support member 4 is fixed against rotation.

The pivot pin 5 has a side protrusion 1 at its upper end.
5, the projection projects into a recess in a member 16 supported in the connecting bridge 1. The members are axially movable via guide members 17,18. The element 16 is provided with a recess on its right side, into which a lateral projection 19 of the sleeve 20 projects, which sleeve is arranged in a right-hand pivot axis configured as a hollow shaft 12'. It is supported for axial movement.

The sleeve 20 has a central hole in which a cylindrical pin 21 is rotatably supported. The upper end of the cylindrical pin 21 is configured as a double member, in which a tongue 23 is provided, the double member being axially movable with respect to the tongue. When the tongue piece 23 is rotated, the double member 22 and, by extension, the cylindrical pin 21 are inserted so as to rotate together.

The lower end of the cylindrical pin 21 is configured as a threaded pin 24, which leads to a second pivot pin 25 configured as a sleeve with an internal thread.
It has plunged into the upper part of the body. The pivot pin is also axially movably supported in the hollow shaft 12'.

The lower end of the pivot pin 25 is connected to a web 26a of a support member 4' having a focus adjustment member 3'.

In order to elastically connect the axially movable sleeve 20 and the pivot pin 25, a spring 27 is provided between them.

The tongue 23 projecting into the double part 22 is part of an axle pin 28 , which is fixedly connected to the drive knob 30 via a screw 29 . The drive knob 30 is formed as a circular plate whose flat underside is provided with five holes and a sector-shaped recess 35 . One of these holes is indicated visually in FIG. 2 by the reference numeral 31. Claw member 32
is formed as a bent leaf spring, which surrounds the pin 36 and thereby fixes its position. The free end of this leaf spring is
It is bent upward so that the pawl member 32 can protrude into the notch 31 when the drive knob 30 is rotated. When the drive knob 30 further rotates, the pawl member 3
The upwardly bent end of 2 jumps out of the hole 31 again. The zero position of the drive knob 30 is engraved in correspondence with the position of this pawl member. This zero position is engraved on the upper side of the drive knob 30 as shown in FIG. are doing.

The drive knobs 6 and 30 are provided with sector-shaped recesses 33 and 35 into which protrude pins 34 and 36 fixed to the casing, which are used as stops and therefore actuate. Limit the rotation range of the knob.

To focus the two monoculars 2, 2' together, the drive knob 6 is rotated. As a result, the threaded sleeve 9 also rotates, so the threaded pin 10
moves in the axial direction. The screw pin drives the pivot pin 5 and thus the focus adjustment member 3 via the web 4a. The axial movement of the pivot pin 5 is transmitted via the lateral projections 15 to the member 16, which is thereby moved axially through the bridge 1. In this case, the member is inserted into the sleeve 2 in the right-hand pivot shaft 12' via a lateral projection 19.
0 is driven. The sleeve 20 is the plate member 16
When moving downwards through the
The pivot pin 25 and, in turn, the focus adjustment member 3' are driven via the spring 27. When the sleeve 20 moves upwards, the pivot pin 25 is driven via the threaded pin 24 and in this case the spring 2
7 acts so that the upper end of the sleeve 20 and the lower end of the twin member 22 remain in contact.

That is, when rotating the drive knob 6, the two focus adjustment members 3,
3' move together in the axial direction by the same amount.

To adjust the focus independently, use the drive knob 30.
Rotate. In this case, the shaft pin 28 also rotates the tongue piece 23 and the double member 22 connected thereto. As a result, the threaded pin 24 in the threaded sleeve 20 of the pivot pin 25 rotates, the distance between the sleeve 20 and the pivot pin 25 varying, the spring 27 always being connected to this sleeve. Acts on the elastic connection of the pins.

That is, when rotating the drive knob 30, only the focus adjustment member 3' in the monocular 2' moves in the axial direction, so that the difference in diopter of the operator is compensated for.
